This is the old Russian folk tale. "Sivka-Burka" means chestnut and grey and this is traditional appellation of any horse in the tales, though as a lacquer subjects it refers specifically to the story of young Ivan, who alone of three brothers prays over his father's grave, and is rewarded by the gift of a horse which breathes with smoke and from those ears issues flames. Furthermore, if Ivan climbs in one ear and out of the other he turns into a handsome prince. This, along with Sivka-Burka'' flying powers, enables him to complete for the hand of Princess Elena-the-Fair, who set herself up on the twelve pillars and will only marry the suitor who can jump high enough to snatch her ring. With the horse's help Ivan does this, but then disappears. When a search is conducted for the successful suitor Ivan remains as a poor peasant/s son in order to test the princess's love. She recognized him and they married.
